1. General description
PESD1FLEX in a small SOT23 (TO-236AB) Surface-Mounted Device (SMD) plastic package
designed to protect two automotive FlexRay bus lines from the damage caused by ElectroStatic
Discharge (ESD) and other transients.

2. Features and benefits
• Due to the integrated diode structure only one small SOT23 package is needed to protect two
FlexRay bus lines
• Max. peak pulse power: PPPM = 200 W at tp = 8/20 μs
• Low clamping voltage: VCL = 40 V at IPP = 1 A
• Ultra low leakage current: IRM = 1 nA
• Typ. diode capacitance matching: ΔCd/Cd = 0.1 %
• ESD protection up to 23 kV
• IEC 61000-4-2, level 4 (ESD)
• IEC 61000-4-5 (surge); IPPM = 3 A at tp = 8/20 μs
• Small SMD plastic package
• AEC-Q101 qualified

3. Applications
• FlexRay bus protection
• Automotive applications
